A Rehoboth Beach home accidentally caught fire early Saturday morning. Around 8 a.m. fire crews were called to a fire at 29 Dove Knoll Dr. in the Dove Knoll Development at Midway just off of Coastal Hwy. It took firefighters nearly two and a half hours to put the fire out. No one was injured, but the fire caused an estimated $100,000 in damages. The Delaware Fire Marshal says the fire started in the attic of an attached garage and caused an electrical malfunction.
